If I am reading your post correctly your no3 is 7.5? it should be no higher then 0.5 I would suggest water changes and have your phosphates checked as well algae thrives on phosphates.

"Kh 4.9 13.7"
I am confused by this. Dkh should be around 9-10 and I'm unsure as to what the 13.7 is for.
You can raise alkalinity with sodium bicarbonate but has to be gradual or it might affect your Ph to where it may be deleterious to the whole system. Read more on this.
Let us know and we can probably give you a better informed recommendation.

How did you introduce it to the tank? I had this happen recently when I introduced a green variety to the tank. It died off, then the orange variety that was already in the tank started to shrink back. Turned out there were little tiny white Nudibranchs that came in on the green frag.
